Armor plate for vehicles

Inventors: Wanninger, Paul; Kruse, Jurgen;
Assignee: Daimler-Benz Aerospace AG (Munchen, DE)
Primary Examiner: Johnson; Stephen M.

Attorney, Agent or Firm: McGlew and Tuttle
An armor plating for vehicles has at its outer side a layer (13) of plastics material bound explosive containing radar absorbing materials. |
|
DETAILED DESCRIPTION OF THE INVENTION In FIG.
1 a plate shaped module 1 of the external layer of the inventive armor plate is depicted which consists of an outer layer 2, a middle layer 3 and an inner layer 4.
The outer layer 2 consists herein for instance of 20 to 50% by weight of aluminum and/or carbon fibers and 50 to 80% by weight of plastics material binder, for instance HTPB.
The central layer 3 is composed from 20 to 50% by weight of carbon fiber and/or titanium dioxide and 50 to 80% by weight of HTPB.
The inner layer 4 consists of 90 to 95% by weight of explosive material, for instance nitropenta and 5 to 10% by weight of HTPB.
The thicknesses of the layers amount herein respectively to 3 to 5 cm for the outermost layer 2, the central layer 3 and the innermost layer 4.
According to FIG.
2 the plate shaped module 5 is structured in a homogeneous manner.
It consists for instance of 65 to 70% by weight of explosive material, for instance nitropenta, 20 to 25% by weight of radar absorbing material, for instance carbon fiber as well as 5 to 10% by weight of plastics material binder.
The layer thickness of the module 5 can, for instance amount to 10 cm.
In FIG.
3 an explosive material layer 7 is provided in front of a main armor 6 of steel.
Plates 8, 9, 10 of an inert material, for instance, steel,are placed ahead of the explosive material layer 7.
The plates 8, 9, 10 extend obliquely with respect to the main armor 6.
They overlap each other and are spaced from each other by spacers 11 in the form of webs.
Thus passages are formed between the plates 8, 9, 10 through which the explosive material of the layer 7 can penetrate, as is indicated in FIG.
3 by the boundary layer 12.
The outer layer 13 of the inventive armor plate follows adjacently to the boundary layer 12 and the plates 8, 9, 10.
In order to achieve a high adhesiveness at the boundary layer 12, thus a common matrix of the external layer 13 and the explosive material layer 7 into which the plates 8, 9, 10 are embedded, the external layer 13 and the explosive material layer 7 incorporate the same or a similar plastics material binder
